4. Project Objectives To study the working principle of gas and smoke detector system To design and construct of the gas and smoke detector system and control system using Arduino with Bluetooth module To implement gas and smoke design in the project At the very first time of smoke creation so that avoided the unwanted accident

5. Literature Review A smoke system is number of devices working together to detect and warm people through visual and audio appliances when smoke and carbon monoxide. A smoke detector is a device that senses smoke,gas .

6. Features Of MQ-5 Smoke Sensor The MQ-5 smoke sensor is sensitive to smoke and to the following flammable gases: High sensitivity LPG Natural gas Town gas Butane Small Sensitivity Alcohol , Smoke

7. Connect MQ-5 Sensor The MQ-5 has 4 pins: Vcc,GND,A0,D0 Right Now I Will Only Deal With 3 pins. Here is how you should connect the MQ-5 to your Arduino Vcc to Arduino 5v GND to Arduino GND pin A0 to Arduino analog pin A5

8. What is Arduino ? Arduino is an open source electronics platform based on easy to use hardware and software. ATmega328 microcontroller(8 bit) Input voltage 5v 32k Flash Memory 16 MHz Clock Speed Operation on +5v 14 Digital I/O Pins(of which 6 are PWM) 6 Analog pins

9. How does it work? When threshold voltage remain at minimum level that time green light still on. When the smoke reaches a certain level, it will make sound a buzzer and a red LED will turn on. Bluetooth system also included this process which gives a signal by SMS on the smart phone.

10. Necessary Equipment MQ-5 gas sensor 5V power supply Male to male to male to female jumper wires Arduino Uno Arduino Bluetooth Module Breadboard LED Buzzer 220 ohm resistor

13. OUTPUT RESULT

14. Application They are used in gas leakage detecting equipment in family and industry It is suitable for detecting of LPG , natural gas , town gas Avoid the noise of alcohol and cooking fumes cigarette smoke.

15. Advantages Detects Products of Combustion Sensitive Enough to detect level of gases Detects gases prior to reaching lethal levels Produced between the Occurrences of detectable level and detectable heat levels

16. Disadvantages Can be Prone false alarms Must be mounted at a low level Can be Poisoned Not Suitable for areas where CO and CO2 and Produced the functions within the area Cannot be considered as a universal replacement and thermal detectors High Cost

17. Conclusion Smoke detector is One of the easiest and low costly. Most of industries use it, Because it work fatly to protect and most effective. In future the use of gas and smoke detection will increases. In future we include Bluetooth Module At finaly we complete this project using 3 sensor
